FIL TER FOR GASOLINE-STOVES.

SPECIFICATION forming part of Letters Patent No. 536,364, dated March26, 1895. Application filed June 4, 1894. Serial No. 513,353- (Nomodel.)

To all whom it may concern.

Be it known that 1, CHARLES S. WHITE, a citizen of the United States,residing at Min-' neapolis, in the county of Hennepin and State ofll/Iinnesota,haveinvented a certain new and useful Improvement inFilters for Gasoline- Stoves, of which the following is a specification.

My invention relates to means for use in [0 connection with gasolineburners for separating foreign substances from the gasoline.

The object of the invention is to interpose a filtering device betweenthe supply tank and burner (in either a heating or lighting 1 5apparatus) which will effectually separate from the gasoline particlesof foreign matter, and also liquid of greater specific gravity thangasoline.

Myimprovements are illustrated in the ac- 2o companying drawings, inwhich- Figure l, is a side elevation of a gasoline stove provided withmy improved filtering device. Fig. 2, is an enlarged detail, in verticalsection, of the filtering device. Fig. 3, is

" a plan View of the filtering device inverted and with the cup portionremoved; and Fig. 4 shows a modification.

In the drawings 1 designates agasoline stove of the usual or anysuitable construction; 2, 3, the pipe for conducting it to the burner orburners; and 4. the burner and usual, or suitable, devices forcontrolling the flow of the liquid.

Ata convenient pointbetween the tank and the burner, preferably on ahorizontal portion of the pipe, is interposed the filtering device 5.This device may be of any convenient or desired form, comprising ahollow body in which the gasoline is compelled to 49 descend into asettling chamber and. rise through a filtering medium before passingonward through the pipe to the burner.

In the form of device illustrated in Fig. 2 a shell 6 is coupled toopposite ends of sec- 5 tions of the pipe 3 and has a pendent tubularportion 7 in communication with the inflow portion of the pipe. Abovethe lower end of this tube 7 is a filter or screen 8 of finely wovenwire-cloth or other material suitable for the purpose. A cup 9 isscrewed onto the shell 6, or otherwise suitably connected to its base,to provide a chamber for retaining solid substances, or water, &c., thatmay be introduced through the in-take pipe. At the bottom of this cup isa screw-plug 10 which can .55 be removed when necessary to permit thedischarge of such matter as may have accumulated in the chamber of thecup.

- In use, as will be apparent, the gasoline, in passing from the tank tothe burner descends 6o first into the chamber of the cup, as indicatedby the arrow to, and thence canpass onward toward the burner only byrising through the filtering medium 8, as indicated by the arrow 2;;whereby heavy particles, as well as liquid heavier than the gasoline,are allowed to settle in the chamber of the cup, and light particles,which might otherwise pass onward, are caught by the strainer 8.

In the modification shown in Fig. 4, instead of the pendent tube 7, apartition 11 is substituted and so arranged that the liquid may passfreely downward at one side of the partition and flow onward onlythrough a filtering medium 8, as in the other form of construction.

Other modifications within the same plan of operation will readilysuggest themselves to one skilled in such matters.

By. use of a filtering device of the charac- 8o ter suggested the mostcommon causes of explosions and accidents in connection with the use ofgasoline stoves and other gasoline burners are avoided. The mostfrequent causes of trouble arise from particles of solidmattertemporarily obstructing the small appertures at the burner; or theadmixture of water with the gasoline at the point of ignition; and ineither event the flame maybe extinguished, while the flow of gasolinemay 9c continue, so that when subsequently ignited it will causedisastrous explosions. These dangers are obviated by the presentimprovement, for solid substances, as "Well as heavy liquids, will becaught and retained in the 5 filter cup.

.Having described my invention, what I' claim is- 1. The combinationwith a pipe for conducting gasoline to the burner; of a filtering de-100 vice consisting of a two part shell the upper and having apendentinternal inflow connecportion of which is connected with thepipetion formed integrally therewith, a second and provides an inflowconduit to the lower shell detachably connected to the first and :5portion, a screen above the mouth of the inproviding a settling chamber,and a screen 5 flow connection, whereby the lower member above the mouthof the inflow connection and is made a settling chamber and the gasolinebetween it and the outflow pipe, substantially is forced to rise throughthe screen to the as and for the purposes set forth.

outflow portion of the pipe substantially as V T w and for the purposesset forth. CHARLES IO 2, The combination with a pipe for conduct-Vitnesses:
